3 Range profile phases
This section describes the 3 phases that are required to perform the first range
measurement after reset, using the VL53L0X.
There are 3 phases:
• Initialization & load calibration data
• Ranging
• Digital housekeeping - see Section 6.2: Limit settings.
3.1 Initialization/calibration phase
The initialization/calibration flow is described in Figure 5: Initialization flow on page 11.
All initialization functions are defined in Section 4: System initialization/calibration on
page 13.
initialization/calibration phase should be run only after reset or system/setup change.
3.2 Ranging phase
The ranging flow is described in Figure 6: VL53L0X API ranging flow on page 12.
The first range measurement (after reset) has to be preceded by an initialization and
calibration flow.
Basic functions used in the ranging flow are described in Section 5: Ranging on page 15.
